Abstract: An engine device including a cylinder block having one side portion to which a flywheel that is rotated integrally with a crankshaft is disposed. The engine device is provided with a starter that transmits a rotational force to the flywheel at a time of engine start. A flywheel housing, which accommodates the flywheel and includes a starter attachment pedestal for attaching the starter, is attached to the one side portion of the cylinder block. The starter is disposed inner side of the engine than a portion of the flywheel housing, the portion being located outermost in the engine with respect to a direction that is perpendicular to a direction along a crankshaft center and that is parallel to the cylinder head joining surface of the cylinder block.
